Specification of Letters Patent. Patented Dec, 26, 1916,

Application led November 12, 1912. Serial No. 730,888.

l cording machines of lthat type which include a series of type-carriers mounted in lateral alinement, a series of stops selectively settable to limit movement of the type-carriers, and a series of keys each of which is capable of successive operations for the purpose of setting one or more stops to limit movement of any desired number of type-carriers.

One type of machine to which mypresent invention is particularly well adapted is described and illustrated in Hopkinss patent, Number 1,039,130, issued September 24:, 1912. In the accompanying drawings I have illust-rated my invention lembodied in and combined with an adding and recording rmachine constructed in accordance with the adding and recording mechanism described and illustrated in the said Hopkins patent. I have shown my invention embodied in and combined with such a machine for the purposes of convenience only, and it will be apparent to those skilled in the art to which the invention relates, that the entire invention, or essential parts thereof, are equally as well adapted for use yin other machines. The

adding and recording machine of the saidV patent is well known commercially as the Dalton adding machine.

Onel object of the present invention is to produce an improved arrangement of stops to limit the movement of the type-carriers -in their excursions, so as to dispense with the necessity of la movable carriage for setting the stops, without increasing the number Aof the numeral keys which correspond to the numericall alphabet, theresbeing one key for cachot the ten numeral figures.

l, Another object is to vvrovide mechanism for' restoring the stops ti) idley position be- `upon a shaft` 46.

forejoperation of therecording mechanism, at the will of the operator, so that when error is made in striking the keys such error may be corrected and will not be entered in the added and listed items. y

With these and other objects in view I have illustrated oneform of my invention in the accompanying drawings in which- Figure 1 is a longitudinal sectional view vof a machine embodying my invention.

Fig. 2 is a horizontal sectional view above the keys and key levers and stop mechanism, and below the type-carriers and adding mechanism. Fig. 3 is a perspective view of the stop setting devices,and the ends of the Ykey levers by'which the stops are selected. Fig. 4: is a sectional view illustrating the construction and arrangement of the stop selectingand setting devices. Fig. 5 is a perspective view of a portion of the mechanism controlling the stop selecting and setting devices. Fig. 6 is a detail view ,of the connections from ythe total key and the devices for preventing operation of the total key at any time when carrying is incomplete. Fig. 7 is a view showing the position of certain of the parts when the total key is operated. Fig. 8 illustrates one of the total wheel actuating racks in its forward position when taking a total.

VTheDaltonfadding machine as at present on the market, and as described in the Hopkins Patent Number 1,039,130, includes ten `numeral keys l arranged in rows in a key-board and mounted upon levers 2 extending toward the rear of the machine and being pivoted upon a shaft 3. The rear or inner ends of the key levers terminate in projections or hammers 4, arranged in a row the plane offwhichvis transverse to the planes ofthe rowsin which-the keys are arranged.v The said machine also includes a series of type-carriers 5 arranged in transverseV alinements and pivotally supported For each ,of said4 typecarriers there is a rack?, which racks are also suspended from the shaft 6.

A 'main vshaft 8 controls the type-carriers and racks in their parallel movements, 'and operation of said shaft 8 is necessary before said type-carriers and racks may be operated to list or add numbers. This control is effected through a connection from the shaft 8 which includes a link 9, an arm 10 to which said link is pivoted, an arm 11 at each side of the series of type-carriers and racks and one of which is connected to the arm 10 by a pin and slot connection 12, and a rod 13 carried by the lower ends of the arms 11 in front of the vertical extensions of the type-carriers and racks. Forward rocking of the shaft 8, through the connections described, swings forwardly the rod 13, thereby permitting forward movement of the typecarriers and racks, such forward movement being effected by springs 14 connected to rearward extensions of the type-carriers (Fig. 1). The type-carriers have series of type 15 on their forward ends, said type being movably mounted and having their yprinting faces within the arcs of the arcuate type-carriers. A platen or paper support 16 is mounted within the arcs of the type-carriers and is arranged to support the paper upon which the records are made by operation of the type. A type-driving hammer 17 is provided for each type-carrier, said hammers being pivotally mounted upon a supporting rod 18 andbeing actuated to drive the type in printing operations by means of springs 19. The hammers are normally held in idle position away from the type by latches 20. Forward movement of the typecarriers automatically effects the release of the corresponding hammer by rubbing against a lever' 21 and raising the forward end of said lever, thereby raising a corresponding bar 22 which is connected to the corresponding latch 20. The shaft 18 is a rock shaft and supports a bail 23 which is automatically operated on the forward movement of the type-carriers, and said bail at the proper time engages the ends of the bars 22 which are raised by operation of the corresponding levers 21, thereby, pushing said raised bars 22 forwardly and effecting the release of the latches 20 from the hammers 17 which correspond to the typecarriers which move to recording position. The bail passes above the bars 22 which are not raised by type-carriers moving to recording position so does not release any hammers except the hammers corresponding to the type-carriers which move to record. The arrangement and operation of these recording devices is such that thewtype become perfectly alined in printing position adjacent to the paper support 16 before the hammers are released, so that when the hammers strike the type the type will be driven to produce a clear and distinct impression.

The Dalton machine, and the machine of the Hopkins patent aforesaid, also includes a swinging frame 24, having cam slots 25 in the upper ends of the sides of said frame. A rod 26 is supported in the slots 25 and a series of adding wheels 27 are revolubly mounted upon said rod. There is one wheel 27 for each actuating rack 7, and said machine includes provisions for operating the frame 24 to lower the wheels 27 out of mesh with the racks 7 before said racks start on their forward excursions, and raise said wheels into mesh with said racks before said racks start on their return excursions. By cooperation with suitable alining or carrying pawls 28 adding is effected, including carrying or transferring from lower to higher orders in the process of addition. These elements and the means for effecting their operation are not included in my invention and I have not illustrated them in detail. Itis in combination with these known and existing structures that my invention is used, and having thus described the known and existing struct-ure I will now proceed to describe my invention and its relation thereto.

At the rear of the machine is a series of supporting posts 29. Two of said posts support a plate 30 and said plate 30 is connected to the remaining two posts by rods 31. A plate 32 is supported by the rods 31, and said plate has aseries of parallel guide ways 33 within which the depending heels 34 operate. The heels 34 are supported by the racks 7 by pin and slot connections 35 and are actuated downwardly by springs 36 connecting said heels with projections of said racks, respectively. The heels 34 move within the guide ways 33 during the forward and backward excursions of the racks, and prevent lateral movement or oscillation of said racks. The under side of the plate 32 is provided with a series of parallel passages or guide ways 37 There are nine of the passages 37, one for each numerical character or digit except for the digit 9, the front rod 31 constituting a stop for the 9s and dispensing with the necessity of any guide way or passage 37 for the 9 stops. A plate 38 is supported by the rods 31 at the side of the plate 32 opposite from the plate 30. A series of spiral elements 39 are revolubly supported by the plates 30 and 38, there being one of said spiral elements for each of the transverse passages or guide ways 37. The spiral element at the rear extends through an enlarged opening in the plate 30 and at its extending end is journaled in a bracket 40. The adjacent spiral element is also extended beyond the plate 30, but is not provided with any spiral portion on its extended part. The extended part of the adjacent element 39 is also journaled in the bracket 40 and said extensions are provided with intermeshing pinions 4l. The remaining spiral elements are provided with intermeshing pinions 42 so that all of said elements will be rotated together. The spirals of the adjacent elements 39 areoppositely arranged, because their rotation is in .opposite directions, and it is necessary that they feed the stops hereinafter described in the saine direction when rotated.

The upper ends of two of the posts 29 support a rock shaft 43 having arm 44 attached to its rear end and a 'longer arm 45 attached to its front end and terminating immediately over the extension or hammer 4 for the 97 key, so that when the 9 key is operated the arm 45 will be raised and the shaft 43 will be rocked, A series of nine arcuate arms 46 are loosely mounted upon shaft 43, the lower ends of said arms terminating above the extensions or hammers 4 on all of the key levers except the lever for the 9 key upon which the arm 45 rests as above explained. A rod 47 is supported by the arms 44 and 45 above the lower extensions of the arcuate membersv 46, so that when any numeral key lever is operated the corresponding element46 will be rocked, thereby raising the rod 47 and rocking the shaft 43. The arcuate elements 46 extend above the plate 38 and are formed with downwardlyV extending tongues 48 which terminate a slight distance above the upper edges or surfaces of the spiral elements 39 and adjacent to the right side of the guide plate 32. Springs V49, (Fig. 4) are connected to the members 46 and actuate said members downwardly` thereby restoring said members and the 'corresponding keyy levers and keys to idle position after each operation. Y

The spirals on the elements 39 are spaced the same distance apart as kare the passages 33, so that irrespective of the number of complete or partial revolutions imparted to said elements the spiral portions thereof are always between the passages 33 and the grooves or passages formed by said spiral portions are always immediately below` the passage 33. A

The plate 38 supports a series. of tubular magazines 50, inthe present instance there beingY one of said magazines for each ofY the spiral elements 39. For convenience of illustration and operation I have illustrated the 1nagaz1nes50 arranged obhquely, projecting through the plate '38 and arranged to Ydischarge into the groove or channel formed bythe spirals on the elements 39. Each magazine contains a series of spherical stops 51 which, in idle position, are supported by the lowermost one of said stops restingupon the spiral element 39 at the yright of the depending tongue 48 (Fig. 2).

In each magazine there is one stop for each type-carrier and rack, being nine typecarriers and nine racks in the present instance, and, therefore, nine stops. These stops are fed transversely by the spiral elements 39 incidentally to the operation of the numeral keys. In being thus fed transversely the stops are supported by the spiral elements and extend into the transverse passages or guide ways 37, and are thereby prevented from displacement.v The passages 37 intersect the passages 33 (Figs. 6,

7 and 8), so that when the stops are fed transversely they pass across the passages 33, extending into said passages and constituting stops for the heels 34 in the forward excursion of the type-carriers 5 and the racks 7.

An arm 52 (Figs. 1 and 4) is rigid with the rock shaft 43 and supports one end of the link 53 the opposite end of said link being connected to a depending portion of an escapement dog or pawl 54. The said dog or pawl 54 is rigid upon a rod or shaft 55 removably supported between two of' the posts 29 by means `of pivot bearings 56 (Fig. 3). Another escapement dog or pawl 57 is pivotally supported by the rod or shaft 55, and said two Ypawls are formed so that their edges adjacent to their upper ends abut together (Fig. 5). The movable pawl 57 is connected to the pawl 54 which 1s rigid on the shaft 55 by a spring 58, the tendency of said Vspring being'to draw said pawlsfinto contact with reach other. The pawl 57 projects a slight distance abovethe upper end of the pawl 54 for purposes which will hereinafter appear. y f e The plate 30 has a. depending portion which constitutes a bearing for o-ne end of an escapement shaft 59. An escapement pinion which, in the present instance, is in the form of a ratchet wheel, is revolubly mounted uponthe escapement shaft 59 and is normally engaged by the dogor pawl 54, as clearly illustrated in Figs. 3 and 5. The outer surface of each of the teeth on the escapement pinion 60 is in the. form of an entering oblique plane 61 (Figs. 3 and 5). Since the dog or pawl 57 is slightly longer than the dog or pawl54, it follows that when the escapenient pinion 60 engages the pawl 54 the inner edge of the pawl 57 presses against the outer edge of the tooth of said pinion 60 which is in engagement with said pawl 54, as illustrated in Fig. 5. VVhen the shaft 55 is rocked so as to move the pawl 54 inwardly the spring 58 acts to draw the pawl 57 ciose against the edge of the tooth of the pinion 60 from which the pawl 54 is released. This permits the pinion 60 to be rotated, and assaid pinion rotates the pawl 57 is drawn inwardly under the tooth of said pinion following the tooth released by the pawl 54, the

said pawl 57 pressing inwardly along the oblique plane surface or cut away portion 31. rlhis action places the upper end of the pawl 57 in the path of movement of the followingtooth on the pinion G0 thereby stopping rotation of said pinion GO. Backward rocking of the shaft will cause the pawl 54 to press the pawl 57 from under the tooth of the pinion GO with which said pawl 57 has become engaged, and will move the said pawl 54 under said tooth, this operation being effected because the pawl 54 is somewhat shorter than the pawl 57. Since the escapement shaft 55 is connected with the rock shaft 43, and since the rock shaft 43 is rocked at each operation of a numeral key, it is obvious that the escapement is operated on the depression of each numeral key. The parts of the escapement as well as the rock shaft 43 and the connections thereof to the escapement are returned to their normal or idle positions after each operation of a numeral key by a spring 62 (Fig. 4) connecting the rod 47 with the link 53.

A plate 63 is attached to the shaft 59 and carries a pawl 64 engaging with the teeth of a ratchet pinion G5 which is integral with the pinion G0. A pinion 66 rigid upon the shaft 59 meshes with an actuating rack 67 loosely supported upon a shaft 68 (Figs. 1 and A spring G9 is connected with the rack 67 and actuates said rack to rotate the shaft 59 at each operation of a numeral key, such rotation being permitted by the step bystep movement of the escapement mechanism hereinbefore described. The shaft 59 also supports a pinion 70 which is in mesh with one of the pinions 42, so that whenever the escapement is operated by operation of any one of the numeral keys all of the spiral elements 39 will be rotated effectively to feed from right to left, that is from lower to higher orders, any of the stops 51 which had passed beyond the retaining gates or tongues 48. These elements are arranged in such relation to each other that the stops will be moved at each depression of a numeral key a distance equal to the distance between the guide passages 33 into which the stops extend so as to limit movement of the type-carriers and the racks in their forward movements.

The elongated spiral element at the rear supports a series of spherical stops 71, in addition to the stops 51 normally contained in the magazine 50 to be delivered upon said spiral element. rl`he stops 71 extend into the passages 33 and will be engaged by the heels 34 and prevent movement of the severa-l racks 7 prior to operation of numeral keys. As the numeral keys are operated the stops 71 are moved or fed laterally on to the eX- tended portion of the rearmost spiral element 39, thereby moving said stops 71 from lower to higher orders incidentally to the operation of the keys and incidentally to the selecting and positioning of stops 51 upon and by the several spiral elements 39. Since operation of the numeral keys results in operation of the spiral elements 39 te select and position the stops 51, and to move the stops 71, from lower to higher orders, it follows that reverse rotation of the spiral elements 39 will restore the stops 51 into the magazines 50, and will also restore the stops 7l in their normal or idle positions to prevent movement of all of the racks 7. rThis reverse operation of the spiral elements to restore the stops 51 into the magazines 50, and to restore the stops 71 in the path of movement of the heels 34, is accomplished automatically and incidentally to the listing or adding of a number. The rock shaft 8 supports an arm 72 (Fig. 1) upon which is pivoted a hook 73. rIhe arm 71 and the hook 73 are swung forwardly at each operation of the rock shaft 8. An arm 74 is supported by a shaft 75 and is connected by means of a link 7G with an arm 77 upon the shaft 68. The rack 67 has a projection 78 adapted to be engaged by the. arm 77 when said arm 77 is moved rearwardly, which operation will restore the rack 67 to its idle position thereby rotating the shaft 59 and operating all of the spiral elements 39 in a direction which is the reverse of their operation by the numeral keys. This reverse operation moves all of the stops 51 under the beveled lower ends 79 (Fig. 4) of the tongues or gates 48 and into their respective magazines 50, and also moves the stops 71 back to their normal or idle positions in which they extend into the passages 33 to prevent movement of all of the racks 7 until after the numeral keys have again been operated. Then the shaft 8 reaches the forward limit of its movement, after the number represented by the typecarriers has been recorded, said shaft 8 is returned to its initial position by springs 80 (Fig. 2). At the limit of its forward movement the hook 73 engages an extension 81 (Figs. 1 and 2) thereby drawing with it the arm 74 which, through the link 76 and the arm 77, operates the rack 67, resulting in rotation of the spiral elements 39 effectively to move the stops 51 into their respective magazines and the stops 71 into their normal or idle positions. As the hook 73 reaches its idle position an arm thereof engages with a projection 82 thereby disengaging the hook 73 from the projection 81, and permitting the connections from the shaft 75 to the shaft 68 to be restored to idle position. A spring 83 suitably connected to one of the elements connecting the shaft 75 with the shaft 68 restores said elements to idle position after release of the hook 73. It will be noted that, as in the Hopkins patent, Number 1,039,130, and in the Dalton adding maf chine, the springs 80, in restoring the shaft 8 to idle position, alsoy actuate the connections from said shaft effectively to cause the rod 13 to restore the type-carriers 5 and the racks 7 to their rear or y idle positions, causing the racks 7 to operate the adding wheels 27 to add the numbers recorded and to transfer from lower to higher orders in the process of addition. The said connections also restore the hammers 17 intojengagement with their respective latchesv 20.

Return of the stops 51 into their respecf tive magazines 50 may be prevented at the will of the operator, so that any number set up or represented by said stops maybe repeatedly recorded or added without repeated setting of the stops. Y The mechanism for enabling the operator thus to repeat a number comprises a device for, preventing .engagement of the hook 73 with the projection 81, s0 that said hook may ymove back and forth without yoperating the stop return devices. This repeat mechanism includes a key 84 mounted in or adjacent to the rows of keys 1 and having the lower end ofits stem pivoted to a lever 85 which is operatively mounted on a support 86. y The rear or inner end of the lever 85 has pin-and-slot connection with a bell-crank device 87 which is pivotally mounted upon a support 88, and one end of which extends substantially vertically at the side of the arm 74 which supports the projection 81. Theupper end of the vertical arm of the bell-crank device 87 is provided with a laterally extending shield or flange 8,9l adapted to be operated under the projection 81 and constitute a surface against which the hook 73 may rub when said hookis operated forwardly in listing or adding a numberas previously described. When the shield or flange 89 is positioned under. the projection 81 engagement of the hook 73with said projection will be prevented, so that thenumber set up or represented by the stops 51' may be recorded or addedas many times as desired without returning said sto s to idle position.

A spring 90 (Fig. 1) is e ective to hold the j key 84 in its elevated position, and to hold the shield or flange 89 normally away from the projection 81, so that depression of the repeat key 84 is necessary in orderto prevent engagement of the hook 73 with the projection 81 and permit thenuinber to be repeatedly recorded or added.

On some occasions error may be made in striking the numeral keys f thereby resulting in selecting and setting the wrong stop 51, which would result in4 an error in the item listed and added unless corrected. For restoring the stops to idle position independently of operation of the type-carriers and racks I utilize a train of connections where- .the key-board in or adjacent to the rows of numeral keys 1, and -operating in a slotted giuide92 which is encircled by a spring 93., The spring 93 normally holds the key 91 in its elevated adjustment but permits manual depression of said key. The

, Stem of the key 91 is provided with a slot 94 which receives a pin 95 carriedby an arm 96 whose front end kis pivotally supported at 97. By this means operationfof the key 91 will oscillate the arm 96. vThe rear or inner end of the arm 96l is pivotally connected to a link 98 the upper end of which is pivoted to an arm 99 attached to the shaft 75. The shaft 75 is a yrock shaft land has a pin 100 engaging kbehind a shoulder 101 on the hub of the arml74, thereby permitting the arm 74 to be operated by the hook 73 without moving or disturbing the shaft 75. However, downward movement of the arm 99 will rock the shaft 475 in a direction to cause the pin 100' to swing the arm 74 and the connections from said arm 74 rearwardly, causing the arm 77 to engage lkey to the shaft 75 to theiry idle positions,

and permitting the spring 83 to restore the connections from the shaft 75 to the shaft 68 to their idle positions.

In order to `print the total contained or represented in the adding wheels 27, and to operate the type-carriers 5 jand the racks 7 in connection with said adding wheels in clearing operations, it is necessary that said parts be permitted to operate without restraint by the stops 71. A key 102 has a stem extending through the key-board plate and pivoted at its lower end to a lever 103 mounted upon a support 104. The rear or inner arm of the lever 103 is pivotally connected with one arm of a bell-crank lever 105, another arm of lever 105 is pivoted to a link 106. c The rear end of the link 106 is connected to a lever 107 the upper end of which is pivoted to an arm 108, which is attached to a rock shaft 109 (Figs. 1 vand 6). Two arms 110 attached to the rock shaft 109 extend forwardly and support a rodwlll under rearward extensions of the movable heels 34 which are carried by the racks 7.

Elevation of the rod 111 will engage the rearward extensions of the heels 34 and raise said heels above the stops 71 and permit movement of the racks 7 in clearing operations. Depression of the key 102 will operate the connections above described effectively to raise the rod 111 and permit operation of the racks 7 and the type-carriers in total printing and clearing operations, although such operation is prevented prior to the completion of carrying or transferring, in the process of addition, so that one forward and backward movement of the rock shaft 8 is necessary after the listing of any one or more items before the total key may be depressed.

One of the posts 29 supports a pivoted cam 112. The plate 63 has a pin 113 (Fig. 6) which, in idle position, presses upon an arm of the cam 112 and holds said cam rearwardly against an abutment 114. lVhen any numeral key is depressed the pin 113 is raised by the rotation of the escapement shaft 55, thereby removing said pin 113 from the arm of the cam 112. One side of the swinging frame 24 supports a pivoted arm 115 having a pin 116 extending over the upper edge of the cam 112. A bellcrank lever 117 is pivoted at the side of the cam 112 and said cam and said lever are actuated toward each other by a connecting spring 118. In idle position the pin 116 is engaged behind the upper arm of the bellcrank 117, thereby holding said arm forwardly, and the pin 113 is engaged upon the arm of the cam 1.12, thereby holding said cam rearwardly, thus extending and tensioning the spring 11S connecting said cam and said lever.

IVhen the numeral key is operated the shaft rotates and raises the pin 113 permitting retraction of the spring 118 and permitting forward movement of the upper portion of the cam 112, moving the shoulder of said cam under the pin 116 and raising said pin above the upper end of the lever 117. This permits the spring 11S to move the upper end of the lever 117 under the pin 116, movement of said lever 117 being limited by an extension 119 thereof engaging with a stud 120 upon the link 116. Thus the lever 117 is positioned to constitute an abutment for the link 106 and prevent operation of the total recording and clearing mechanism during the time that any of the stops 51 are in position upon the selecting and positioning devices 39. As previously explained the frame 24 is swung backward and forward during the listing and adding of numbers. Then said frame is swung rearwardly to draw downwardly the adding wheels 27 previous to the forward movement of the type-carriers and racks in adding and listing operation, the pin 116 rubs along the upper edge of the cam 112. Just previous to starting of the type-carriers and racks, on their return, the frame 24 is swung forwardly by suitable devices (not shown) and the pin 116 moves forwardly along the upper edge of the cam 112 and also along the upper edge of the lever 117, but does not engage behind the upper end of said lever 117, thereby leaving said lever in position to constitute an abutment to prevent operation of the link 106 and its connected parts. Assuming that the escapement shaft 55 has been operated to actuate the selecting and setting devices 39 to restore the stops 51 into their respective magazines, it is apparent that the pin 113 engages the projections of the cam 112 and restores said cam to idle position, leaving the pin 116 resting upon the upper end of the lever 117. Another operation of the frame 24 will move the pin 116 rearwardly beyond the upper end of the lever 117, and said pin 116 will drop behind the upper end of said lever 117. Forward movement of the frame 24 will then cause the pin 116 to engage behind the upper end of the lever 117 and draw the same forwardly in opposition to the spring 118, thereby moving the front end of the lever 117 below the stud 120, leaving the total printing and clearing mechanisms free for operation at the will of the operator. On this blank or idle stroke operation of the racks 7 and the typecarriers 5 is prevented by engagement of the sliding heels 34 with the stops 71. The operation of the machine in clearing operations is substantially the same as in the machine of the Hopkins patent and in the Dalton adding machine.

In the machine of the Hopkins patent and in the Dalton adding machine, there is a series of stops for each type-carrier, and a movable carriage whose operation is necessary for the purpose of positioning said stops. MyA present invention not only dispenses with the use of the movable carriage, but includes novel selecting and setting mechanism whereby the ten numeral keys may be utilized for setting a field of stops, in any desired relation, to represent the numbers t0 be listed and added. My present invention includes a series of stops, and ten numeral keys whereby said stops may bc set without the use of any intermediate stop setting carriage.

While I have shown and described one preferred form and embodiment of my invention, it is apparent that there may be various changes and alterations in the construction and arrangement of the various parts without departure from the spirit and scope of my invention, and I do not restrict myself to the identical construction and arrangement shown and described.

What I claim and desire to secure by Letters Patent is:

l. In an adding machine, a'series of stops, mechanism for selecting and positioning said stops, a device for actuating said mechanism, keys determining when said actuating device may operate, and a series of magazines arranged to receive said stops and to contain said stops in their idle positions.

2. In an adding machine, a series of movable stops, stationary supports for said stops, and means for selecting and moving from said supports certain of said stops While the remaining stops remain in idle position on said supports.

3. In an adding machine, a series of later'- ally movable stops, stationary supports for said stops, and mechanism for selecting and moving laterally from said supports selected ones of said stops While the remaining stops remainin idle position on said supports.

1. In an adding machine, series of laterally movable stops adapted to be positioned to represent numbers, stationary supports for said stops, a rotary positioning device for each series of stops, and mechanism for operating said positioning device effectively to move said stops from said supports and to position said stops to represent numbers.
